LAMP-BURNER.

" Specification of Letterslfatentl 1 5113911133( 1 Jul-y 8', I919.

Application filed January 14, i919. Serial No. 271,077.

To all whom it may concern:

Be it known that I, WILLIAM S. HAMM, a citizen of the United States, and resident of Hubbard Voods, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to burners for oil lamps. It is found in practice that where a lamp provided with such a burner is subjected to a sharp jar, the flame is sometimes extinguished, evidently by reason of a momentary separation of the unignited vapors from the flame; and it is the object of the invention to provide means for overcoming this difficulty. To this end the invention consists of a burner provided with a movable element which is held in position by a resilient support.

The invention is shown as applied to a well known form of burner comprising a round wick tube carrying at its upper end a cup which may constitute a combustion chamber, and when given the shape as illustrated acts as a flame spreader. This cup is made the movable element.

In the drawings Figure 1 is a side elevation of an auto truck tail lamp, a portion being broken away to show the burner in elevation; and

Fig. 2 is a detail sectional view of the burner taken on the line 2-2 of Fig. 1.

While the improved burner is applicable to lamps intended for any class of service, the tendency of the flame to be extinguished by jarring has been found to exist, particularly in tail lamps of auto trucks, and for that reason the invention is illustrated in connection with a lamp intended for such service.

The body 10 of the lamp is provided with an attaching bracket 11, by which it may be secured to a vehicle. Within the body there is located an oil font 12, having its burner, generally designated by the numeral 13, so positioned that the flame is in line with-a light-emitting aperture closed by a lens 14. The body 15 of the burner is adapted to be fitted to the font 12, and is shown as having a threaded neck 16 for effecting such connection. The wick 17 is shown as round and as extending upwardly through the body 15, and through a correspondingly shaped burner tube 18 projecting upwardly from the body. A flame spreading cup 19, of any, desired shape, is slidingly mounted upon the tube 18 and is normally held against an outstanding flange 20 at the upper end of the tube by means of a helical spring 21, reacting against the top of the body 15.

The spring 21 is sufficiently weak to yield under the influence of the momentum of the cup 19, yet strong enough to normally hold the cup against the flange 20 and thus retain it in proper position for performing its usual function. vided with a short sleeve 22 which encircles the wick tube.

It is desirable also that the cup may be The cup may be protiltable under the influence of lateral jars.

This movement is provided for-in the con struction illustrated by making the sleeve 22 a loose fit on the wick tube. If the sleeve were omitted the cup might have a somewhat closer fit on the tube.

The efficiency of the device in the form illustrated has been fully demonstrated in actual practice. Various changes, however, may be made in the details of construction without departing from the scope of the p v invention.

While the flame spreader is shown in cup form, the invention is applicable to spreaders of varioustypesg indeed, the invention will include any burner having a resiliently supported element at the zone of combustion, the yielding of which, under jarring influences, will prevent the separation of the unignited vapors from the flame.

I claim as my invention- ,1. The combination with a burner having a wick tube, of a flame spreading cup slidingly mounted on the tube, and means for resiliently supporting the cup.

2. The combination with a burner having a wick tube having a lateral rim at its upperv ing a, Wick tube, of a flame spreading cup tiltably mounted on the tube, and resilient means for supporting the cup in upright position.

5. The combination With a burner having a Wick tube, of a resiliently supported flame spreader.

Copies of this patent may be obtainedfor five cents each, by addressing the 6. An oil burning lamp having a resiliently supported element arranged to flank the flame.

7. A lamp having a burner provided with a resiliently supported element approximately at the zone of combustion.
